Upset that the woman had turned down his romantic advances, a Minneapolis man urinated in his co-worker’s water bottle, authorities say.

Conrrado Cruz Perez, 47, was charged with two counts of adulterating a substance with bodily fluids, according to the criminal complaint filed against him in Ramsey County District Court.

The first count is a gross-misdemeanor; the second is a misdemeanor.

Deputies responded to a Perkins restaurant in Vadnais Heights last October after a 42-year-old employee at the restaurant reported that she was being harassed by a baker.

She told investigators that she noticed several occasions over the past few months when the water bottle she keeps at work tasted like urine, the complaint said.

The incidents started after the woman told Cruz Perez, her co-worker, that she only wanted to be friends after he expressed a romantic interest in her, authorities say.

Cruz Perez initially denied tampering with the woman’s water bottle when deputies first interviewed him about the allegations, but later admitted to once urinating in the container after investigators suggested they might conduct DNA testing on the bottle, the complaint said.

Cruz Perez said he had to go to the bathroom when the incident occurred but that the restaurant was too busy at the time for him to use the facilities, authorities say.

He added that he forgotten to throw away the water bottle after relieving himself in it, according to the complaint.

The woman told investigators that she noticed a taste of urine in the bottle about 15 times over the past several months.

Cruz Perez made his first appearance on the charges last week.

His attorney, Adriel Benjamin Villarreal, said his client had not yet entered a plea in the case.

“We haven’t made any decisions at this point,” Villarreal said.

He declined to comment on the allegations made against his client.

Cruz Perez could not be immediately reached for comment.

His criminal record consists of a handful of parking tickets.

A manager at Perkins said Cruz Perez previously worked as a baker at the restaurant but was fired immediately following the allegations.
